Preventive Maintenance
Inspect and clean brine tank and screen filter on end of
brine pickup tube once a year or when sediment
appears in the bottom of the brine tank.
Injector Screen and Injector
The injector is the component which creates the
vacuum necessary to draw the brine into the water
conditioner. Clean the injector and injector screen once
a year in order to maintain proper water conditioning.
Some locations may require more frequent injector and
screen servicing. Refer to Figure 19 and complete the
following steps to clean the injector screen and injector.
1. Unplug the wall mount transformer.
2. Shut off water supply or put bypass valve(s) into
bypass position and remove the rear cover.
3. Relieve system pressure by opening valve
number 6 (at rear) with a screwdriver (Figure 15).
4. Using a screwdriver, unscrew and remove the
injector screen and the injector cap.
5. Clean screen with a fine brush. Flush with water
until clean.
6. Using a needle-nose pliers, pull the injector straight
out.
7. Squirt water into the injector screen recess of the
valve body to flush debris out.
8. Clean and flush injector.
9. Lubricate the O-rings on the injector, injector cap,
and injector screen with silicone lubricant and
reinstall.
Important: Do not overtighten the plastic cap. Seat the
cap lightly into position. Overtightening may cause
breakage of the plastic cap that may not be
immediately evident.
10. Reinstall cover, reconnect electric power, and reset
the time of day.
11. Slowly open the water supply valve or return the
bypass valve(s) to the “not in bypass” position.

Water Meter
In rare instances, the turbine wheel of the water meter
may collect small particles of oxidized iron, eventually
preventing the wheel from turning. The turbine wheel
may be serviced as follows (Figure 20):
1. Shut off the water supply or put bypass valve(s) into
bypass position.
2. Relieve system pressure by opening valve
number 6 (at rear) with a screwdriver (Figure 15).
3. Loosen and remove the fasteners that hold the
meter adapter to the tank adapter and the
fasteners that hold the piping boss or bypass valve
to the meter adapter.
4. Remove the meter adapter, being careful not to
misplace any of the O-rings.
5. Using a needle-nose pliers, grasp one of the four
vanes of the gland and, pulling straight out, remove
the gland from the adapter.
6. Carefully remove the turbine wheel from the
housing. Using a toothbrush, lightly scrub the iron
off the magnet. Iron buildup on the wheel surfaces
may be removed by soaking the wheel in a mild
sodium hydrosulfite (e.g., RoVer*) solution for a few
minutes, then flushing thoroughly with water.
7. Carefully reinstall the turbine wheel into the
adapter, being certain that the shaft of the wheel
seats into the bearing of the adapter and that the
“dimple” on the wheel faces you.
8. Carefully reinstall the gland into the adapter, being
certain that the shaft of the wheel seats into the
bearing of the gland; press the gland all the way in,
being sure the wheel rotates freely.
9. Reinstall the meter adapter, O-rings, piping boss,
or bypass valve, tighten all fasteners and re-
establish the water supply to the system.
10. Check for proper water meter operation by opening
a downstream faucet and observing the water flow
indicator light on the 460i display.
